Jodi Arias hearing: Judge moves pretrial hearing to September 16

( -- Jodi Arias will have to wait a little longer before the start of her penalty phase retrial.

Judge Sherry Stephens did not set a date Monday for the retrial, waiting until she reviews defense motions that were filed last week. However, she did set a date and time -- September 16 at 11:30 a.m. ET -- to hear arguments on those motions.

Arias, who was convicted on May 8 of first-degree murder in the death of her ex-boyfriend Travis Alexander, briefly appeared at the Phoenix hearing in a striped jail uniform, with her wrists in shackles and her hair wrapped in a bun.

The motions under consideration include two issues Arias' defense attorneys have raised.

The attorneys want to limit or ban live TV coverage of her retrial, citing concerns about her right to a fair trial. They say live coverage during her first trial led to death threats against them and their witnesses.

The attorneys are also asking Stephens to force prospective jurors to turn over information about their Twitter accounts. Arias' attorneys say that even if new jurors refrain from discussing the trial, nothing is stopping other people from reaching out to them on social media with information that may influence their decision. The attorneys say the only way to monitor this influence is for them to know about the jurors' accounts.

At a hearing in July, Stephens said she wanted to start the retrial in late September, but Arias' defense team is pushing to have it start sometime next year.

Stephens' time frame is now looking unlikely as she considers these other matters.

Arias' retrial will apply only to the penalty phase of her trial. A new jury will be selected, and it will decide only whether she will be sentenced to death via lethal injection or life in prison.

In May, a penalty phase mistrial was declared after a deadlocked jury said it couldn't decide whether to sentence Arias to death for the murder of Alexander in 2008.

Earlier that month, the same jurors had taken less than two hours to decide that she was "exceptionally cruel" when she stabbed Alexander 29 times, slit his neck from ear to ear and shot him in the face. They pronounced her guilty of first-degree murder after 15 hours of deliberations.
